Google's move may reduce uncertainty, but it certainly does not remove it.
(1) The licensing material you quoted is for Google's own patents, it has not (yet?) been updated to reflect sublicensing of licensed patents. We'll have to wait that this is out until we review it.
(2) This move actually casts doubt on past claims that Google owned all the relevant IP, and therefore their RF license made the codec royalty free. How do we know that this time, Google actually has all the relevant IP?
(3) It's been stated that 11 entities contributed to the MPEG-LA patent pool that Google licensed, but it's not known at this time who they are or what patents specifically they are licensing. It is not clear if that information will ever be publicly disclosed. By contrast the MPEG-LA's H.264/AVC patent pool lists all organizations that are part of the poo and all patents in the pool. Even so, the H.264 pool is known to be incomplete; for example Motorola is not a member of the pool and Google has argued that their grant-back obligation does not apply to Motorola's patents. Without knowing who contributed to the pool or under what terms, it's impossible to assess how much IPR risk has been reduced.
(4) There is active patent litigation against VP8. It appears that some key IP stakeholders may not be part of the pool that Google licensed. See e.g. <http://www.fosspatents.com/2013/03/patent-clouds-remain-over-vp8-google.html>.
Google's move is helpful, but it is far from removing uncertainty about its IPR status in my opinion.
Furthermore, since the first round of HTML baseline codec debates, every major browser has gotten on board with shipping H.264. Given that interop is coming to exist de facto, why do we need to declare a baseline at all?
